Hades Airsoft Flat HOP-Up Nub

  • Flat HOP-up nub
  • Compatible with most Airsoft AEGs and GBBs
  • Extend your range and improve accuracy!

If you are looking for better accuracy and range, a flat HOP-up nub should do it! The Hades Airsoft Flat HOP-up nub is designed to apply a stronger HOP-up effect than standard cylindrical nubs and is available in 4mm or 5mm lengths.

The nub is constructed from 3D-printed synthetic rubber and maintains its shape regardless of any pressure applied, guaranteeing even pressure is applied across the nub and transferred to your BB without distortion. An additional advantage of using a harder synthetic rubber than the average is that performance will remain constant, even in lower temperatures.

As with other flat HOP-up modifications, this part is only recommended for those who are experienced working on HOP-ups and we suggest that you measure the window size of your inner barrel to ensure you get the correct size for your build.

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
